The Nayarit mouse or Sinaloan deer mouse (Peromyscus simulus) is a species of cricetid rodent endemic to Mexico. It was considered a subspecies of brush mouse until 1977.
The Nayarit mouse is the smallest mouse within the P. boylii species group, with a head and body length of about 10 cm (3.9 in), and a tail measuring about the same again. They typically also have a shorter snout than other members of the species group. They have tawny fur, with creamy-white underparts and a poorly-defined stripe of darker, almost black, fur down the middle of the back. The limbs are dusky to sooty, with white feet. The tail is hairy, usually darker above than below, and ends in a distinct tuft. [2]
The Nayarit mouse is found only along the Pacific coast of Mexico, from southern Sinaloa to central Nayarit. [1] It inhabits forested terrain [3] in coastal plains and river valleys below 200 m (660 ft), including mangrove swamps, acacia thickets and thorn scrub. There are no recognised subspecies. [2]
Peromyscus is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, Mus musculus. From this relative, Peromyscus species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word Peromyscus comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" is in reference to this agility.
Schmidly's deer mouse, is a recently described species of deer mouse from the mountains of western Mexico. It is part of the highly complex and well-studied Peromyscus boylii species complex. The uniqueness of Peromyscus from this area had long been suspected, but was only formalized in 2004 with the publication of its species description. The species was named in honor of David J. Schmidly, a mammalogist and former president of the University of New Mexico.
